Family members don't like name we picked out

Some people are just rude. 
My mother and sister in law don't like the name we picked out 
It's a little girl 
June Lottie 
My sons name is Jonah. So I think June goes really well and both my husband and I love it 
Why can't people keep their opinions to themselves. 
My mother in laws name is Cathy, which I have always thought was a really boring blah name. But I would never tell her that. Haha
